IDC Low Inductance Capacitors (RoHS)
IDC (InterDigitated Capacitors) 0306/0612/0508
GENERAL DESCRIPTION
Inter-Digitated Capacitors (IDCs) are used for both semiconductor package and
board level decoupling. The equivalent series inductance (ESL) of a single capacitor
or an array of capacitors in parallel determines the response time of a Power
Delivery Network (PDN). The lower the ESL of a PDN, the faster the response time. A
designer can use many standard MLCCs in parallel to reduce ESL or a low ESL Inter-
Digitated Capacitor (IDC) device. These IDC devices are available in versions with a
maximum height of 0.95mm or 0.55mm.

IDCs are typically used on packages of semiconductor products with power levels
of 15 watts or greater. Inter-Digitated Capacitors are used on CPU, GPU, ASIC, and
ASSP devices produced on 0.13μ, 90nm, 65nm, and 45nm processes. IDC devices
are used on both ceramic and organic package substrates. These low ESL surface
mount capacitors can be placed on the bottom side or the top side of a package
substrate. The low profile 0.55mm maximum height IDCs can easily be used on the
bottom side of BGA packages or on the die side of packages under a heat spreader.

IDCs are used for board level decoupling of systems with speeds of 300MHz or
greater. Low ESL IDCs free up valuable board space by reducing the number of
capacitors required versus standard MLCCs. There are additional benefits to
reducing the number of capacitors beyond saving board space including higher
reliability from a reduction in the number of components and lower placement costs
based on the need for fewer capacitors.

TYPICAL IMPEDANCE
10
The Inter-Digitated Capacitor (IDC) technology was developed by AVX. This is the
second family of Low Inductance MLCC products created by AVX. IDCs are a cost
effective alternative to AVX’s first generation low ESL family for high-reliability
applications known as LICA (Low Inductance Chip Array).
